Blackscorn told me that some mom was selling it for her son who said he won it in 1996 as a prize at a game convention. It is signed by the creators/devs of MOO2 and dates back to 1996 (but it is still in a mint condition):
For now I can decipher the signatures of Jim Cowlishaw, Steve Barcia, Ronnie Gauny, Jim McIntyre, Kenneth Burd, Pat Owens, Kevin Albers, Shelly Hollen, Rob Corell and Russ Williams. I need a closer look for the other signatures. Is there anyone else out there with the same picture?
